A patient assessment should be completed before the evaluation is performed. This includes an assessment of the patient's ability to tolerate the procedure and an evaluation of any contraindications to the procedure. The sonographer or examiner should obtain a complete, pertinent history by interview of the patient or patient's representative and a review of the patient's medical record, if available. A pertinent history includes:

• Current medical status
• Prior vascular/cardiovascular history & surgeries
• Current, pertinent medications or therapies
• Review of vascular-related risk factors such as hypertension, hypercholesterolemia, peripheral vascular disease, family history of aneurysmal disease, advanced age, and smoking.
• Review symptoms of aortoiliac disease; aneurysmal vs. occlusive disease, back pain, increased pulsation of abdomen, groin, or popliteal fossa.
• Review signs/symptoms of distal emboli and buttock/thigh claudication.
